This invention relates to mine cars and contemplates the provision of a welded mine car body which is resiliently su ported by wheel. axles in such a manner as to ge capable of easy and quick removal therefrom.

rlhe invention further contemplates the -provision of a new and improved means for 'derframe are detachably mounted on and supported by wheel axles.

A still further object of this invention is the provision of a mine car including a body supported by wheel axles, the latter being 0,0..

mounted in journal boxes having integral upwardly extending spring pockets which extend into spring pocket guides formed as parts of the underframe of the mine car body;

- the construction resulting in a shock absorbing mounting for the body and ermitting easy and quick disassembly of the ody from the supporting axles.

Other objects and advantages of this invention will be apparent from the following de'- scription taken Awith the accompanying` sti'ening the body at'that)end of the body drawings in which:

Figure 1 is a side elevation of the car of the presentinvention, certain parts being broken away to more clearly disclose thesupporting portions or elements for the body.

Fig. 2 is a top plan view of the mine car of the presentl invention.

Fig. 3 is an end view of thev car, taken 'V at thegate .end thereof, and

Fig. 4 is a partial end and sectional view on the line 4-4, Fig..2. v Referring now more particularly to the drawings in which similar characters of reference designate similar 'parts in the several views, the car of the present invention comprises a body A mounted on and secured to l an underframe B, the body end underframe being carried `and supported by axles Csupported by wheels D.

bottom or iioor 2 formed, in the instance shown, of a single metal plate having its side edges upwardly flanged as at 4 and overlapping the lower edges of side walls 6 and to which the flanges 4 are connected by being 3 welded to the side walls, as shown at 8. The car of this inventionis designed for end discharge of lading and hence isprovided with an end gate 10 pivoted in ears 12 carried by and preferably welded tothe inner surfaces 60 of the side walls Gat their rear upper corners, as shown more clearly in Fig. 3. For stiifening the side walls 6 the upper edges thereof are outwardly beaded as at 14 and said walls are further provided with vertical posts 16 El;

welded as at 18 to said walls. In the instance, shown in the drawings, the posts 16 are shown` as straight bars, but obviously within the spirit ofthe present invention these stiifening posts may assume any preferred ordesired 70 form, such as angles, channels, or the like. The opposite'end of the body is closed by a fixed end wall 20, beaded as at -22 along its upper edge and having its loweredge inwardly ianged as at 24 torest upon and be 75 welded to the bottom 2. Forconnecting the fixed end wall 20 and the side wall 6, angles 26 are employed which are welded as at 28 to the said side walls and said iixedend wall;

the angles 26 serving also as a means for as will be apparent.

The end gate 10 is provided with a latch 30 adapted to be operated by suitable lever means 31, said latch extending through a iv sills 36,'cl1annel-shaped in the instanceshown,

38 of which the body 1s W5 to the upper anges connected by suitable fasteners such as. the rivets 40. The underframe also includes channel end sills42 which` are connected to the ends of the .side sills b weldin or in any manner wellknown in t e art an which 10P extend from side to side of the body A tol support the latter at its ends; the channel end sills 42 being preferably deeper than the side sills 36 and facing outwardly to support 5 bumpers 44 arranged respectively o each side of the draw bar; it being understood that a draw bar is provided at .each end of the underframe.

Connected to the end sills 42 and extending rearwardly therefrom are spaced draft sills 46 between which the draw bars 48 are mounted for movement as shown more clearly in Fig. 2. For stifeners, gussets 50 are provided which connect the end sills and. draft sills, and other` gussets 52 are provided for stiening the connection of the side and end sills (see Fig. 1). The underframe of the car of the present invention also includes spaced cross-bearers indicated generally at D and each formed of spaced channels 54 arranged back to backand extending between the side sills and connected to the latter by suitable means such as the gussets 56 welded thereto; the draft sills 46 extending to said cross-bearers D and being' connected to one of the channels forming the same by being welded thereto. The cross-bearers D` are connected by a longitudinally arranged channel 58 (Fig. 2) which extends between adjacent channels 54 of the cross-bearers Df and is welded thereto in any rsuitable or desired manner.

Beyond the side sills the body A is also reinforced by angles 60 riveted as at (S2-tothe bot- 85 tom; there being two of such elements 60 shown in the drawings, but obviously as many as are required may be provided. The body A is also connected to the cross-bearers D by being riveted thereto as shown at 64.

Formed at each end of each of the crossbearers D is a spring pocket guide indicated generally in Fig. 2 at G and each formed of elements connected to the channels 54, said elements including spaced vertical wear' plates 66 welded to the channels 54 and the.

outer plates 66 resting against and beingconnected as by welding to the webs of the adjacent side sills. These wear plates 66 are also connected, preferably by welding, to top plates or top spring seats 68, the latter, if desired, being spot welded or otherwise suitably secured to the under surface of the bottom or floor 2.

As clearly shown in Figs. 1 and 4, the axles' C extend transversely of the car beneath the car body and underframe and are journalled in journal boxes 7 0 having upwardly extending integrally formed spring pockets 72 carrying springs 74\; the pockets 72 extending into the guides Gr, see Fig. 4, and the journal boxes having guide lugs 76 adapted to bear against the flanges 78 of guide channels 80, the webs 82 lof which latter extend upwardly and lie against the webs of the channels 54 of the cross-bearers and define the remaining elements which form the spring pocket guides; the webs 82 of said channels 80 beinor connected in any suitable manner as by welding to the webs of the channels 54 of the cross-bearers. The lower ends `of the guide '10 channels are connected by a key 84, as shown clearly in Fig. 1.

, From the description herein it is believed that the construction of the car of the present invention will be fully apparent to those 75 skilled in the art. The car of the present invention is so constructed and desi ed thatA should it bedesired to remove the ody and underframe from the axles it is necessary to remove the keys 84, whereupon the body and 30 underframe may be elevated by means of A jacks, or may be lifted by suitable tackle to immediately free the axles from the underframe. The car of the present invention comprises a body formed of metal elements connected together by welding thereby providing a substantially unitary structure, suitably reinforced and stren hened to provide a rugged construction w ich will Wwithstand service conditions. Further, it will be apparent that due to the specific arrangement of the underframe members including the side sills, cross-bearers, and draft sills,

"and the connection of the end sills to the side sills and draft sills, buing shocks received by the bumpers 44 will be transmitted from the end `sills to the rugged side sills, thus relieving the body per se, including the floor or bottom 2 and the side walls 6 of the stresses resulting from such buing shocks. Replacement of parts when occasion de mands is comparatively easy and simple to The drawings herein disclose one embodiment of the invention, but it is to be understood they are for illustrative purposes only and various changes in the form and proportions of the construction shown may be made within the scope of the appended claims without departing from the spirit of the invention'.
